Operations that take less than a second with either workload running alone can now take many seconds, sometimes the better part of a minute! You might want to try removing the call to pmtimer_init() in ioemu/hw/piix4acpi.c -- the pmtimer emulation is rather broken (burns 25% of a 3GHz cpu). I've just done this in xen-unstable. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
